I'm diving into the world of used PC parts and have my eye on a 7800X3D listed for 350 euros nearby. This is my first purchase of a used CPU and I'm uncertain about what to look for and how to ensure a safe transaction. I don't own an AM5 motherboard yet, so I'm especially cautious. I'm hoping to get some advice on how to check it out before buying! Also, the seller mentioned that it comes with a receipt and warranty, but I'd love to hear any tips that could help me make a better decision. Here's the link to the listing with pictures: https://imgur.com/a/0sqUUMv

When you check the CPU, look for signs like bent pins or any discoloration that could hint at water damage—like orange or red tints. During testing, see if it reports all specs correctly and check if each core boosts as expected. Keep an eye on the voltages; they should be stable!
If this is a private sale with no warranty, make sure to see the CPU running in person. Don’t settle for videos or pictures. If the seller can't show it working right then I'd reconsider the purchase. Just so you know, a brand new 7800X3D in Europe isn't much more than 350 euros—could be a good deal or not!
In Finland a new one is around 430 euros, so that’s why I thought the used one was a steal!
AM5 CPUs are generally pretty safe to buy used since they’re robust compared to older models. Just ask the seller to test it in front of you and get some pictures for assurance. That should help you feel more secure in your purchase!
I checked Amazon for different countries and they range from €400 to €450, so make sure you're getting a fair price!
